WHEN YOU STROLL into the austere modern bar at IndeBleu (707 G St. NW; 202-333-2538), look on the white granite counter for a glossy orange brochure that resembles a tourist's pocket guide to downtown attractions. Unfolded, the familiar image of a Metro map serves as a cocktail menu, with a Lycheetini (vodka and fresh lychee juice) replacing Franconia-Springfield on the "Martini Line," and a blackberry mojito (imagine the minty Cuban favorite muddled with fresh blackberries) on the outer reaches of the Red -- sorry, "Bleu" Line. ...From its mid-December opening through the beginning of March, IndeBleu went through 10,000 copies of it. People take them home, "and we love that," says Mark Gundersen, IndeBleu's communications director. Among those impressed by it are the Library of Congress, which plans to add a specimen to its cartography collection, and Department of Transportation employees, who asked for unfolded copies to hang in their offices.
